Menopause can wreak havoc on mood and body temperature as it signals the end of fertility, but some of the biggest changes it causes are in the brain. Emily Jacobs, assistant professor in the department of psychological and brain sciences at UC Santa Barbara, explains how the precipitous decline in estrogen during the "change of life" disrupts the endocrine system, and why menopause makes some women feel like they're going crazy while others sail through unscathed. Plus: Hear from real women describing the wide range of effects they experienced.

Bonus: Special appearance by Ms. Giffords herself.

One in three cases of Alzheimer's disease may be preventable, but some cases are quite predictable. Dr. Richard Isaacson, Director of the Alzheimer's Prevention Clinic at Weill Cornell Medicine, explains how scientists look at genetics, lifestyle, and medical history to evaluate an individual's risk of developing the disease.

What happens in a child's brain to cause seizures, and why have children with epilepsy been so stigmatized? In this encore presentation, Dr. Stieg talks with pediatric neurosurgeon Caitlin Hoffman, MD, and neuropsychologist Heidi Bender, PhD, to provide a primer for parents, classmates, and teachers. Plus... How best to help if you see someone having a seizure.

In this encore presentation of one of our most popular episodes, Dr. Stieg talks to psychiatrist Richard Friedman about the neuroscience of fear: How parents can transmit anxiety to their kids, how some babies seem hard-wired for anxiety, and why a little anxiety is good for you (but too much is like a burglar alarm that sounds all the time).

Microbes in your intestine are talking to cells in your brain all the time – and what they say can affect everything from inflammatory diseases to psychiatric disorders. Microbiologist David Artis, PhD, and psychiatrist Conor Liston, MD, PhD, explain the connection between your microbiota and your mind – and how to influence their conversation. Plus… another reason to avoid unnecessary antibiotics

Diagnosing and treating attention deficit disorder can be tricky – not every hyperactive kid has ADHD, and some very calm children are extremely inattentive. Pediatric clinical neuropsychologist David Salsberg, PhD, explains what part of the brain is "asleep" in those with true ADHD, and how to identify kids who need intervention. Plus… when is medication really necessary?

From drug cocktails to deep brain stimulation, there is new hope for brain-injured patients with "locked-in syndrome" in minimally conscious states. Dr. Nicholas Schiff, Professor of Neuroscience at the Feil Family Brain and Mind Research Institute at Weill Cornell Medicine, tells the dramatic stories of patient reawakenings from ​comas lasting many years.

What happens in our brains when we're confronted with decisions? And why do some people dread making decisions more than others? Dr. Gregory Berns, neuroscientist and Professor of Neuroeconomics at Emory University, explains that there are different brain systems involved in the decisions we make. When faced with choices, we want to pursue pleasure and happiness as much as we want to avoid pain and negative outcomes. Decision making is also about projecting ourselves into the future and how much uncertainty we can handle.

​Dogs and the humans who cherish them have a unique bond unlike any other. We wonder all too often, do our dogs love us as much as we love them? What are they really thinking? Are we projecting our own feelings onto t​hese treasured family members in trying to understand them? Emory University neuroscientist Dr. Gregory Berns, has made some extraordinary findings. After spending years using MRI imaging technology to study the human brain, he then used this same approach to study dogs' brains. It turns out that our furry friends are much smarter than we thought!
